Drilling Imaging Industry Insights: Core Value And Global Application of GYGD-IV Borehole Imaging System

In the global field of geological exploration and infrastructure non-destructive testing, drilling imaging technology has evolved from traditional "discontinuous core sampling interpretation" to "real-time borehole wall visualization logging," becoming a core technical means for overseas marine development, underwater dam testing, pile foundation borehole quality assessment, and geothermal reservoir exploration. The GYGD-IV borehole multifunctional imaging system developed by our company integrates in-hole dynamic video recording, high-definition fixed-point photography, and text annotation functions. Its technical parameters and operational efficiency fully meet the scenario-specific needs of the global drilling imaging market, making it a benchmark product among mid-range equipment in this field.

The GYGD-IV system excels in three core dimensions of drilling imaging equipment: environmental adaptability, imaging resolution, and operational stability. In terms of environmental adaptability, its probe adopts a 316 stainless steel shell with epoxy spray coating, featuring 96-hour salt spray corrosion resistance and a rated pressure resistance of ≥15MPa (equivalent to 150m hydrostatic pressure), suitable for multi-scenario operations such as marine exploration in seawater environments, underwater dam testing in tropical high-humidity areas, and well repair in arid regions of the Middle East. In terms of imaging resolution, the system is equipped with a 1/3-inch color CCD sensor with a minimum illumination of 0.1Lux, supporting 8x digital zoom and 360° horizontal rotation and 180° tilt adjustment of the lens for full-circumference scanning of the borehole wall. Even in low-light environments of ≥500m deep wells, it can maintain image clarity, enabling quantitative identification of micro-defects such as rock joints (width ≥0.1mm) and pile bottom sediment (thickness ≥1mm), fully complying with international pile foundation integrity testing standards such as ASTM D6760 and BS EN 1536. In terms of operational stability, the transmission cable adopts a double-layer structure of "inner TPU insulation + outer Kevlar braiding" with a tensile strength of 250KG, effectively eliminating frequent cable water ingress failures in field operations; the main control unit uses an integrated injection-molded ABS/PP alloy shell with IP65 protection rating, combined with a low-power embedded dual-core processor, which can achieve 8-hour continuous data collection with a portable 220V generator, perfectly adapting to remote off-grid operating environments such as African mining areas and the Australian outback.

In global application scenarios, the functional design of the GYGD-IV system is highly compatible with overseas market demands. In the infrastructure field, it is mostly used for pile foundation borehole quality testing in the renovation of old bridges in Europe and the United States—for example, in the bridge foundation repair project of the UK’s Network Rail, the system accurately locates structural defects such as borehole wall collapse and concrete segregation through the linkage of a 0-9999m range depth encoder and borehole wall imaging, ensuring that the vertical bearing capacity of pile foundations complies with the EU EN 1997-1 standard; in Southeast Asian regions with rapid urbanization such as Vietnam and Indonesia, the high portability of its main control unit (430×350×150mm, 2.6kg) can meet the needs of manual handling and rapid deployment in mountainous construction scenarios, with operational efficiency 40% higher than traditional equipment. In the field of water conservancy and marine engineering, the 8-level brightness adjustment function of the system’s front-mounted LED array can cope with high-turbidity well water environments in regions such as Saudi Arabia and the UAE in the Middle East, clearly imaging the morphology of well wall scaling and casing corrosion, providing intuitive basis for optimizing well repair schemes; in coastal European countries such as Norway and the Netherlands, its corrosion-resistant probe is used for pile foundation testing of offshore wind farms, capable of withstanding long-term seawater erosion and realizing periodic monitoring of underwater pile integrity. In the field of resource exploration, the system’s dynamic video recording function can visualize the distribution of ore body fractures in Australian iron mines and Canadian lithium mines, providing geological basis for mine roadway support design; in Icelandic geothermal development projects, it provides direct data support for optimizing geothermal well completion technology by identifying permeable fractures in thermal reservoirs, helping to improve geothermal extraction efficiency and aligning with the global trend of clean energy development.

As a core product of China’s drilling imaging equipment "going global," the GYGD-IV system not only meets the stringent technical specifications of high-end markets such as Europe, the United States, and the Middle East but also provides cost-effective solutions for emerging markets. Its stable performance in extreme environments and compliance with international standards help global customers overcome underground visualization technical challenges, improve project acceptance efficiency, and ensure compliance with local regulatory requirements. With the continuous rise in global demand for infrastructure upgrading and clean energy development, the company will continue to iterate drilling imaging technology based on the GYGD-IV system, providing better technical support for the sustainable development of the global geological exploration and engineering testing industry.
